Is 45-degree astigmatism severe?

　　Mild astigmatism and myopia have minimal impact on vision. However, if left uncorrected or untreated, these conditions may progressively worsen, developing into moderate or high astigmatism and myopia. This not only impairs visual acuity but also adversely affects daily life and work performance. So, is 45-degree astigmatism considered severe?

　　Is 45-Degree Astigmatism Severe?

　　An astigmatic axis of 45 degrees falls within the range of low-grade, minor astigmatism and is therefore not considered severe. Astigmatism primarily arises from genetic factors, environmental influences, and improper eye-use habits. Common clinical symptoms include blurred vision, decreased visual acuity, visual fatigue, head or neck tilting, and headaches. Prompt medical evaluation—including visual acuity testing, refraction examination, and corneal curvature measurement—is essential for timely diagnosis and management. Corneal refractive surgery is a common treatment for astigmatism; laser ablation of the corneal epithelium modifies the cornea’s surface curvature, effectively correcting corneal astigmatism.

　　The most fundamental treatment for astigmatism is corrective eyewear—either spectacles or contact lenses designed specifically for astigmatism. Additionally, surgical correction is available. Such procedures are commonly referred to as excimer laser or femtosecond laser surgery; however, candidates must meet several preoperative criteria. The most basic requirements include being at least 18 years of age, having stable refractive error (no significant change) over the preceding six months, having discontinued contact lens wear recently, and being free of ocular conditions such as conjunctivitis or keratitis.

　　Patients should practice appropriate eye hygiene in daily life—avoid reading while lying down or resting the head on the arms—and maintain a balanced routine of work and rest. We hope this information proves helpful to you.
